This page provides an overview of the available methods on the Chainstack Optimism nodes. Go ahead an try the interactive examples as well.

The table has three columns:

  • Method — method name.
  • Availability — out of the box on a regional or global node, or on request on a dedicated node since it requires customization.

📘

The list may not be comprehensive but serves as guidance. In general, if the method is available in op-gethor in op-erigonand it's an eth_ method, then it's available on your Chainstack node.

If there's a method missing, you are unsure, or just have any questions, talk to us. We love talking to developers 💙🛠️.

eth_accountsReturns list of accounts stored on the node. Will always return empty because Chainstack doesn't store any.

net_peerCountWill always return 0x0 on op-geth and op-erigon. The p2p networking is done on the op-node, which does not have an endpoint exposed. See also OP issue 5745.
